Equinor finds oil near Visund field in Norwegian North Sea

The discovery is estimated to contain recoverable resources of 1.3 to 3.6 million standard cubic metres of oil equivalent.

Equinor and its partners have made oil discovery after drilling the wildcat well 34/6-5 S located in production licence 554 in the Norwegian North Sea.

Situated in the Garantiana West prospect near the Visund field, the well encountered 86m of oil column in the Cook formation.

Additionally, the exploration well encountered sandstones in the Nansen formation. The exploration target, however, is classified as dry, as the reservoir is aquiferous.

The exploration well’s primary target was to prove hydrocarbons in the Cook formation from the early Jurassic period while the secondary target was to determine the potential for hydrocarbons in the Nansen formation from the early Jurassic/late Triassic period.

Partners estimate the discovery to hold recoverable resources between 1.3 and 3.6 million standard cubic metres of oil equivalent. This corresponds with eight to 23 million barrels of oil equivalent.

Equinor exploration and production south senior vice-president Rune Nedregaard said: “This is the first Equinor-operated well in the production licence, and the fifth discovery on the Norwegian continental shelf this year.

“The discovery is in line with our roadmap of exploring near existing infrastructure in order to increase the commerciality.”

Equinor has conducted a formation test at the well. This indicated ‘good flow qualities with stable flowing pressure and low pressure drop’. It also showed consistent pressure build-up.

The licence partners, including Vår Energi and Aker BP, are planning to develop the discovery by tying it to the Garantiana field development project.

The West Hercules drilling rig was used to drill the well 34/6-5 S. The platform will now undertake drilling activity at the pilot hole in production licences PL272 and 035 in the North Sea.

In March this year, Equinor and partners made a significant oil discovery in the Blasto prospect near the Fram and Troll fields in the Norwegian North Sea.
